Temperature:Plug culture: 22-24 ˚C until radicle emergence and then reduce to 20-21 ˚C. The temperature can be lowered on approximately day 5. Once cotyledons have expanded lower the temperature further to 18-20 ˚C.

Growing on: Maintain temperatures > 13 °C nights for the first 6 weeks to initiate flower bud development; night temperatures can be lowered further to 10 °C to encourage basal branching and compactness; however – lower temperatures may also substantially decrease the number of flowers initiated; growing at cooler temperatures will produce a higher quality plant. An ADT (average daily temperature) of 19 ˚C will give the fastest finished crop.

Fertilization:Plug culture: Maintain an EC < 1.0

Growing on: Fertilization: Feed at 100-200 ppm nitrogen. Under high light conditions, apply an ammonium-based feed (17-5-17).To prevent stretching under low light conditions apply a calcium-based feed (14-4-14). Under high light and long days an ammonium-based feed (20-10-20) is preferred.
